The Sun Hydraulics DNDAXNN299 (DNDAXNN299) is a solenoid-operated 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This valve is constructed with a solenoid tube assembly that is fatigue rated for service up to 5000 psi (350 bar), ensuring robust performance in high-pressure environments. The direct-actuated design eliminates the need for minimum hydraulic pressure, enhancing its versatility in various applications. A notable feature of this valve is its manual override options, which include choices such as no manual override or temporary actuation detents available in specific models. However, it\u2019s important to note that manual override functionality does not support weatherized coils. The cartridge utilizes a wet armature design where the working fluid surrounds the armature, potentially impacting performance if the coil remains energized for extended periods. This can be particularly relevant when using fluids like water-glycol mixtures that may degrade under heat exposure. The valve supports a wide range of coil termination and voltage options, with some configurations offering surge protection and IP69K-rated connector options for enhanced environmental resilience. Engineered with Sun's floating style construction, this cartridge minimizes risks of internal binding due to excessive installation torque or machining variations. It fits into a T-31A cavity and belongs to Series 1, with a flow capacity of up to 10 gpm (40 L/min). The valve boasts quick response times typically around 50 ms and can handle switching frequencies up to 15,000 cycles per hour. With a maximum leakage rate of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar), this model is efficient and reliable for demanding applications. The DNDAXNN299 weighs approximately .60 lb (0.30 kg) and requires specific installation torque between 30-35 lbf-ft (41-47 Nm).

This solenoid-operated 4-way, 2-position cartridge is a direct-acting, balanced spool directional valve.
- The solenoid tube assembly is fatigue rated for 5000 psi (350 bar) service.
- This valve is direct actuated and requires no minimum hydraulic pressure for operation.
- This cartridge has several manual override choices, including no manual override. See the CONFIGURATION section. Please note: Manual override functionality is not compatible with weatherized coils.
- On models equipped with the D or L control, the detent mechanism in the manual override is meant for temporary actuation. The D, L and T manual control assembly has a mechanical life expectancy of approximately 7,000 cycles.
- Cartridges with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.
- This valve utilizes a wet armature design. This means that the working fluid surrounds the armature and is exposed to the heat generated by the coil. This can be a factor if the coil is energized for long periods of time. Some fluids, notably water/glycol mixtures, break down at these temperatures over time and form varnishes that will affect the function of the cartridge.
- A wide variety of coil termination and voltage options are available, with and without surge protection. See the CONFIGURATION section.
- The solenoid's unique magnetic design results in a high efficiency solenoid, yielding high spool actuating force per Watt expended, leading to reliable valve shifting.
- Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted on the tube in either direction.
- Coil connector options offer ratings up to IP69K. See individual coil product pages for details. Additional weatherized coils and kits are available for more complete environmental protection.
- Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
